Application filed June 28, 1926. Serial No.-119,144.

The object of this invention isto provide a machine for forming ridge caps employed in connection with sheet metallic roofing, the machine including a forming plate and a cooperating element or elements by means of which the plate or strip of sheet metalis' first bent into channel form, and a plurality of rolls for forming the flanges of the channelin the manner required in the finished product.

A further object is to provide a roll rotatable about an axis extending transversely of the path of travel of the sheet and having a convex central portion engaging the inner wall of the channel, and a'plurality of cooperating rolls mounted .on axes inclined with reference to the axis first named, the cooperating rolls having a circumferential channel or concave portion for engaging the outer surface of the sheet.

With the foregoing and other objectsin view, the invention consists in the novel construction and arrangement .of element-s described, illustrated and claimed, it being understood that modifications may be made within the scope of the claims, without departing from the spirit of the invention.

In the drawings forming part of this application,

Figure 1 shows the rolls and mounting the base being in vertical transverse section Figure 2 is a section on line 22 of Fig-r ure 3.

Figure 3 is a View of the machine in side elevation.

Figure 4 is a perspective view, showing certain of the forming elements.

A shaft 10 mounts a driving pulley 11 on one end, and on the other end a gear wheel 12 adapted to mesh with gear wheel 13 mounted on a shaft 14 which in turn mounts lower forming roll 15.

The roll 15 includes the convex central portion or circumferential ortion 16, and tapered annular shoulders 1 and this roll carries bevelled gear wheel or pinions 18 and 18' thru which drive isimparted from shaft 14 to beveled gear wheels 19 and 19.-

The wheels last named are formed with the rolls 20 and 21 each having an annular groove, such as 22, and an annular portion 23 constituting a face for cooperation with tapered surfaces 17 of roll 15. The rolls 20 'ing provided with a and 21 are mounted on axles or shafts 24 and 25, these being inclined as shown, in Figure 1, and the angle of inclination being such that the surfaces 23 are directlyopposite the ta ered annular shoulders 17, and the flange or annular portion 26 of the upper rolls are opposite the shoulders 27 of roll 15.

The shafts 24 and tions 31 and 32, and thru the latter screw bolts such as 33 extend and engage the nuts on bolts 24 and 25, lock nuts being :shoWn at 34. The shaft 10 is mounted in bearings 36 and 37 supported by brackets 38, 39, carried by longitudinal channel bars 40 and 41 constituting a base.

The shafts 24 and 25 are mounted in brackets 41 and the latter are slidable or adjustable with reference to'brackets 42 carried by or formed with elements 38 and 39. Adjustment is provided by means of screws 44 passing thru the end portions 45 of ele- ;nfents 41, and retained by lock nuts 46 and A bar 50 extends longitudinally of the machine, mounts strip 50 and i's'mounted on V-shaped brackets 51 carried by channel bars 40 and 41 of the frame or base. A forming plate 53 extends over bar 50 and is spaced therefrom as shown in Figure 2. The sheet of metal roofing .bein formed passes between bar 50 with its strip 50 and plate 53, and is'guided' between pins 54 and 55 on bar or brace 56. The sheet is further guided by bars 57 and 58, and is formedby the structure of Figure 4 into an inverted V channel, from which it passes to the structure of Figure 1. The plate 53 may be formed as illustrated in Figures 3 and 4, be-

curved edge at 53, on each side'thereof, and plate 53 is supported by the V-shaped bracing elements 59 having an offset at 59 to provide a space 60 thru which the plate passes, in the forming operation.

Having thus described the invention, what is claimed is:

1. In a ridge cap forming machine, a plura'lity of rolls each provided with an annular channel and with plain annular work engaging surfaces, these rolls being rotatable about axes inclined with reference to each other, and a third roll mounted between the N T o F F 1 c Y JESSE FULENWIDER, HARRY FULENWIDEB, EDWARD W. NORRIS, OF SAVANNAH, GEORGIA, ASSIGNORS TO SAID ROBINSON, Am) HARRY 's 25 extend thru a shaped bracket 30 having angular end por- .2. In a ridge capforming iuaclnnefaplurality of rolls each. provided with an annular channel and rotatable about axes inclined with reference to each otlier, anda thirdroll mounted between the rolls first named and having a central circumferentialconvex portion spaced from the walls of he channel of the rolls first named, the third roll including tapered annular shoulders and the re maining rolls having cylindrical portions opposite said annular shoulders.

3. In a ridge cap forming machine, a plu ralityof rolls each provided withan annular channel and rotatable about axes inc-lined with reference to each other and a third roll mounted between the rolls first namedand having a central circumferential convex portion spaced fromthe walls ofthe channel of the rolls first named, said-third roll including outer beveled surfaces and 'thc'channeled rolls including surfaces complementary tothebeveled portions gear wheels carried by the third roll, and gear wheels rigid with the rolls first namedand driven by the. gear wheels on the third Mill.

4. In a ridge cap formingmachine a plurality of rolls each provided with an annular channel and rotatable about axes inclined with reference to each other, and third roll mounted between the rolls first named and having a central circumferential convex portion spaced from the walls of the channel of the rolls first named, the-third roll including tapered annular shoulders and the remaining rolls having cylindrical portions opposite said annular shoulders and means for adjusting the position of the rolls first named.

5; In a ridge cap forming n a'chine,a'plu rality of rolls eachfprovrded 'wi'thnn 'a'nnu lar channel and rotatable about "axes in- :clined with reference to each other, and a third roll mounted between the rolls first named-and having acentral circumferential convex portion spaced from the walls of the channel of the rolls first named, the third roll including tapered aImular-shoulders and the remaining rolls havingcylindrical por tions opposite one of the annular shoulders on each side'of the third roll, and having flanges adjacent to the cylindrical portions and opposite the other 'tapercd annular shoulder of the third roll.

6. In a ridge'cap forming machine abar extending longitudinally of the path of movement of a sheet to'be formed, a forming plateof inverted channel shape mounted in spaced relation to the bar and abovethe latter, a lower forming roll mounted beyond 'the'plate andhaving aconvex surface, and

upper forming rolls having annular channels therein, the channel portions being on opposite sides of the-convex portion of the lower roll, the upper rolls being rotatable above axes converging in an upward direction.

In testimony whereof we aflix our sigma-- tures.
